Type material: C. edychroa : originally two syntypes in SML, one possible syntype now in MNHN (labelled “ Holotype ”), worn and lacking its apex ( Fig. 30 View Figs 27–33 ); very doubtful syntypes AMSA C.6988 (not seen). C. edychroa var. violacea : not located. P. gracilis : Holotype in BMNH (ex Macandrew coll.), 3.0× 1.1 mm. M. anxia : syntypes AMSA C.27446, 1 syntype NMWC 1955.158.912 (not seen).

Regional locality data: SOUTH AFRICA: KwaZulu-Natal: Kosi Bay , 1–4 km S of estuary, - 20–22 m (D. Herbert & K. Bloem; NMSA V2284 ) ; off Kosi Bay , - 23–24 m (D. Herbert & K. Bloem; NMSA S2936 About NMSA ) ; SE of Kosi Bay , - 50 m, fine sand (Kilburn et al.; NMSA E5349 About NMSA ) ; off Kosi Bay , - 9–17 m, stone washings (D. Herbert; NMSA D9928 About NMSA ) ; between Kosi Bay and Bhanga Neck , - 13 m, sand (D. Herbert; NMSA S2995 About NMSA ) ; same data but - 10–12 m, sand (D. Herbert; NMSA S2373 About NMSA ) ; off Boteler Point, - 70 m, coral rubble (Kilburn et al.; NMSA E1574 About NMSA ) ; off Island Rock, - 62 m, sand and coral debris (Kilburn et al.; NMSA E5562 About NMSA ) ; off Leadsman Shoal , - 24–26 m, stone washings (D. Herbert & Natal Parks Board; NMSA E 2636 About NMSA ) ; Sodwana Bay, Two-Mile Reef , - 10–15 m, stone washings (D. Herbert & R. Broker; NMSA E 734 About NMSA ) ; off Richards Bay , - 50 m, fine sand, broken shell ( CSIR Water Research; NMSA A 6102 About NMSA ) ; off Cape St Lucia , - 76–80 m, coarse sand (Kilburn et al.; NMSA E 5692 About NMSA ) ; SE of Mission Rocks , - 50 m, old coral rubble (Kilburn et al.; NMSA E 6297 About NMSA ) ; off Durban Bluff , - 20–22 m, sand (R. Kilburn & R. Fregona; NMSA B 5468 About NMSA ) ; Aliwal Shoal, off Umkomaas , - 27 m, silt between rocks (G. Smith; NMSA E 1677 About NMSA ) . Eastern Cape: Port Grosvenor , - 82 m, worn coral nodules (Kilburn et al.; NMSA S 9578 About NMSA ) ; off Cape Morgan Lighthouse, east of East London , approx. - 100 m, broken coral and shell (A. Connell; NMSA B 7122 About NMSA ) .

Distribution: New Caledonia to Queensland, west to Réunion I. and south-eastern Africa, south as far as the East London area, in shallow water to about - 100 m.

Remarks: The types listed above have been examined, except for M. anxia , photographs of a syntype of which ( Fig. 31 View Figs 27–33 ) were kindly provided by D. Beechey. The protoconch of a fresh Réunion I. specimen, donated by Dr Maurice Jay, is illustrated here ( Fig. 33 View Figs 27–33 ).

K. edychroa shows some resemblance in teleoconch form to Mangelia lutaria Hedley, 1907 , of New South Wales, type species of Exomilus Hedley, 1918 . In fact, M. anxia , here synonymised with K. edychroa , was included in Exomilus by Powell (1966). However, the protoconch in Exomilus lutarius , as figured by Laseron (1954: figs 251, 252), has a distinctive, cylindrical, truncate shape, without trace of diagonally cancellate sculpture.
